At colorFabb we have a well-equipped 3d printing studio with many popular 3d printers. Our grade of Economy PETG has been tested using various 3D printers, which has resulted in the following recommended settings.

Adviced 3d printing temperature:235C-255C

Adviced 3d print speed:30 - 50 mm/s

Advised Heated bed (if you have one, not strictly necessary):70-80C

Cooling fan75/100% fan cooling for best aesthetics, this gives best performance on overhangs and small details. For best mechanical performance try printing with the least amount of cooling needed, for optimal layer adhesion.
